A ALGAMATOR.

Specification of Letters Patent. 7 Pate ted D 1914 Application filed November 22, 1913-. Serial m. 802,431,

Be it known that I, ARTHUR J ROBINSON,

a citizen of the'United' States, and a'resident of Sheridan, in the county of Sheridan and State of Wyoming, have invented a new and Improved Amalgamator, of which the following is afull, clear, and exact description.

My invention relates to an amalgamator in which the sand or pulverized rock is fed to a standpipe from a hopper,and escapes I driven 1n any suitable manner as by a pulley laterally at the base of the pipe through a body of quicksilver. I providemeans within the standpipe to agitatethe sand and to force its passage through'the quicksilver, after which the sand is subjected to washing before being permittedfto escape from the apparatus. V

' The object of my invention isto provide an amalgamator improved in various particulars, to the end thatfeiliciencyin operation may be promoted, as Well as simplicity of construction and control. v

lhe invention consists in the novel features hereinafter described andclainied.

Reference is to be had to the accompany.-

ing drawings forming a part ofthis" spe'cifi K cation, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of an amalgamator constructed in accordance with my invention; Fig. 2 is a horizontal section on the line 22 of Fig. 1; and Fig. 3 is a detail horizontal section on the line- 3-3 of,

Fig. 1. y

In constructing the illustrated embodiment of my invention, a suitable base 10 is provided and any approved framework 11 is erected thereon. A standpipe 12 is provided having a side inlet 12 into which material in the way of sand or pulverizedrock is fed from a -hopper13. The lower sand is forced, as hereinafter described.

which the sand escapes,

The shell has a flaring upper end 15 and the upper edge is below a trough 17 into to finally tail off through a spout 18 on said trough.

Disposed axially in the standpipe 12 is a shaft 19, having "suitable bearings, here shown as consls'tlng of'a stepped bearing 20,

an intermediate sleeve bearing 20 formed on a bracket 20 secured to the interior of i the pipe 12, and an upper flanged bearing. ;20 1n the form of a bushing, ball bearings 21 being provided between the flanged bearmg an'dlauniter pinion 22 securedtothe upperend ofthe shaft. Meshing with the pinion 22' is a bevel pinion 23 on a drive shaft 24; turning in suitable bearings 25 26, which in practice,"will' be belted to any convenient source of power. Any other suitable means may be employed for turning I the shaft 19. 7 I

In order to force the sand downwardly through'the body of quicksilver within the tube 12, and cause it to risethrough' the quicksilver at the extremity of the tube, a

spiral blade 27 is secured to the shaft and given preferably buta single convolution,

and there is provided below the, spiral blade a spiral series of lateral agitating fingers thesebeingprovided'on a head 29 which is securedfto the shaft 19, and taperstowardv the lower end to allow an increas'lngblea'r- "ance for the sand, with a view tofprevent the crowding of the latter as it passes through the lateral openings 14. Additional lateral agitating fingers 30 are disposed on the shaft 19, in various positions above the spiral blade 27, which prevent the sand from banking above said blade. An vannular lining 12 is secured to the tube12 around the blade 27, screws 12. or other fasteners being employed for the purpose, to permit the removal and renewal of the lining. The lining 12 has its upper edge beveled in an inward and downward direction to direct the material towardthe blades'27 and to prevent clogging by avoiding any abrupt shoulder. Thus the lining will receive the wear of the sand as it is forced. downwardly through the quicksilver seal by the blade, and the wearing surface may thus be readily renewed. I

Within the flaring upper end 15 of the shell 15, variously disposed depending nozzles 31 are arranged on branch pipes 32 of a ring pipe 33, which is supported adjacent to the top of the pct 15 by brackets 34 secured to the standpipe 12, said ring pipe being in communication with a supply pipe 35, adapted in practice to be connected with any convenient water supply. A body of water is maintained in the shell and its and the water and the sandvtherein will be agitated by the jets from the various nozzles, whereby the sand will be thoroughly washed and freed from any valuable particles of material adhering 1?) to the same, the sand finally, flowing with the water over the upper edge of the shell to the trough l7, and passing outward throughthe spoutlS. r a I i It is to be understood that in practice, any

15 approved means will be provided'for removclaim as-new, and desire to's ecure by Letters Patent p I n .1. An amalgamator, comprising a supply pipe adapted toreceive the material to be treated, an amalgamating pot surrounding the lower end of the feed pipe and adapted to receive a quicksilver sealfor the pipe, said pipehavinga discharge opening establishing communication with the'pot, a vertical shaft in said pipe, a spiral blade. on said 5 shaft to force the material downwardly, a

head on, the shaft below the blade, thesaid head tapering toward the lower end, and

laterally projecting agitator fingers on said head.

2. An amalgamator, comprising a supply pipe adapted to receive the material tobe treated, an amalgamating pot surrounding the lower end of thefeed pipe and adapted to receive a quicksilver seal for the pipe, said pipe having a dis'charge openingestablishing communication with the said-pot,

a spiral blade on the shaft adapted to force the material downwardly into the pipe and through'the seal, a removable annular lining in the pipe around the said blade, said lining having its upper edge beveled in an inward and downward direction, and agitating fingers rigid with the shaft and disposed both above and below the said blade and the lining 3. In an amalgamating apparatus, an v amalgamating pot, means for feeding to the said pot, near'the bottom, the material to be treated, a water supply ring ad ac'ent to the top of the pot, a series of nozzles depending from the ring and disposed within the upper portion of thepot at varying heights and at different points 'aroundthe pot, means for connecting the ring with a water supply, and means for carryingoff the water and tailings from the pot.

In testimony whereof I have signed my two subscribing witnesses. I I
